Forward Controls Design 1215KM 5.56 Muzzle Brake, 1/2×28
1215KM (1/2 x 28) is our latest offering in the Dead Air sound suppressor mounts line. Threaded for 1/2 x 28, 1215KM is a Keymo compatible brake, compatible with all Dead Air 223 caliber sound suppressors.
1215KM is a single chamber brake, with a baffle like chamber forward of the ports. The tines on top and bottom that connect the Keymo mount to the front chamber are of symmetrical, we think a smaller/thinner top tine to force more gas upward is unnecessary.
1215KM is designed to have less concussion than most brakes. In terms of felt recoil reduction, most brakes are similar in performance. In the old days, some tank guns brakes are nothing more elaborate than a tube mounted perpendicular to the bore forming a T shape, it doesn’t take much to make a brake that works. If one is to look at old tank gun brakes, he will soon realize these tank gun brakes and most muzzle brakes for small arms today bear surprising resemblances and design. To make a brake less offensive is far more difficult. 1215KM follows our design philosophy, it’s a simple and effective brake. It does what it’s designed to do, and does so without making unsubstantiated claims.
We tested the 1215KM against a host of brakes and flash suppressors. Flash suppressors are the least concussive. The one we know to be the most offensive was as loud, concussive and obnoxious as ever. Nothing we don’t already know.
The real surprise is 1215KM’s performance. To wit, even though the Mk12 brake is the 1215KM’s inspiration, it is still an FCD design, we did not use most of the Mk12 brake’s features. The attributes that helped 1215KM even LESS concussive: 30 cal exit hole (we opted to follow Dead Air’s example, instead of making it more 223 based). The ports are not angled like the Mk12 brake. The flat sides of the port don’t direct gas back to the user, or bystanders behind the shooter. 1215KM’s design goals were not only met, but exceeded.
Machined in 4140 steel, heat treated and black nitride.

Very high quality machining and finish on these!
Very nice fit with Keymo as well. I’ve only ran them with a can so I can’t speak on sound or blast effect w/o a can.
